FE 450 is a type of structural steel commonly used in construction and engineering. It is known for its good weldability and high strength, making it suitable for various applications, including bridges, buildings, and other structures. The "FE" stands for "ferrous," indicating that it is primarily composed of iron, while "450" refers to its minimum yield strength of 450 megapascals. This steel grade is part of the European Standard EN 10025, which specifies the technical delivery conditions for hot-rolled products. FE 450 is often chosen for projects that require durability and resistance to deformation under load, ensuring safety and longevity in structural applications.
